ixia: Support of 1 NIC connection to trafficgen
For some testcases it is useful to have only one connection between traffic generator and DUT. Thus IxNet class was extended to support such connection. Feature is enabled if both IXIA ports are set to the same value. New integration testcase ixnet_pvp_tput_1nic was created to demonstrate this feature. Unused code was removed from 3rd_party/ixia/ixnetrfc2544.tcl to simplify introduction of new features and to speed up IXIA configuration.
